When implementing a custom meeting UI, you may notice that there are limits to how many videos can be displayed concurrently. There are limits imposed by Zoom's back end which ensure that the meeting-related services maintain a level of integrity at all times for all users. Below is some information that may help you account for these limits within your application.
(Note: self video, AKA local video, does not count towards these limits)
